ALSA Configuration Trouble
I compiled a new 2.6.8 Debian Kernel and took out the OSS stuff and only enabled ALSA.
I am now having trouble making ALSA work.
I think my problem might be that I have a BT878 TV card and a sound card, but the TV card is at /dev/dsp0 and the sound card is at /dev/dsp1
The symptoms are that any program uses Sound complains, e.g. KDE says "Device cannot be opened for playback (no such device)"
Below is some debugging output.
cat /proc/asound/cards:
0 [Bt878 ]: Bt87x - Brooktree Bt878
Brooktree Bt878 at 0xe5011000, irq 12
1 [Live ]: EMU10K1 - Sound Blaster Live!
Sound Blaster Live! (rev.7) at 0xd400, irq 5
cat /etc/modutils/alsa-base:
# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-emu10k1
# module options should go here
# OSS/Free portion
alias char-major-14 soundcore
